Is there some kind of semi-conducting material in the device, similar to the rings in a choke that you can put around mains cables?

No it does not "choke off / supress" interference induced onto the cable...superior cables are either well-screened or even contain a ferro-magnetic-type RF-choke....for this purpose Furutech makes use of their own technology called GC-303 (found in their power distribution/filtering units and on their top-range cables).

The NCF Booster is constructed from Furutech's proprietary NCF technology; which in short, is a special crystalline material compound that contains nano-sized ceramic particles and carbon powder. NCF effectively gives the Booster (and what it comes in contact with) superior vibration (mechanical and acoustical) dampening properties which is important in a high-end system seeing that vibrations can (and this is well described in technical publications) alter the characteristics of electronic equipment and/or affect the properties of crystals, conductors, etc. This interference results in distortion of the original signal(s), which may compromise the sound/performance of the system. That is, for example, why you (and all of you know this!) pay special attention to having good vibration isolation for your turntable (small signal).

I have a solution: Let us have a demo and see if we cannot cure you from your ignorance? What do you say?

If you agree to be the test subject in a DBT and you can reliably tell me every time they’re in the mix vs not, I’ll buy them. If you can’t you give a pair to every forum member that asks...fair deal, no?

The significance and reliability of DBT’s have been debated since the stone ages....

People’s ears, tastes, opinions, moods, preferences, etc. differs.

What matters to you before you purchase a product is whether YOU LIKE IT OR NOT. It is that simple. Not what your buddy says or I say. Or what the DBT says.

I am simply offering you an opportunity to listen to the NCF Booster (in your own system and with your own ears if you so wish) and make up your own mind whether you like it or not.

Off course not everyone will have the same opinion about a specific product.

It is your prerogative whether you like it or not; and I am definitely not expecting everyone to like what we have to offer. If that was the case then there would be but only one pair of loudspeakers, one amplifier, one CD player, one Turntable, etc on offer in the world that everyone would be buying and be loving! Not realistic.

No Sir! What matters most before I purchase any product, other than Swiss chocolates, is to establish the truth about the product and credibility of he seller. It has nothing to do whether I like or not. Extraordinary claims require extraordinary proof. It really is as simple as that.

No extraordinary claims are being made. I never said this product is better than any other product designed for the same purpose; neither did I claim they are the best in the world. I simply explained its intended function/purpose as a newly launched product.

It is definitely and by all means for you, as the customer, to establish the truth about the product (or for that matter any of our products) by taking them off me and making up your own mind....and our interaction and my level of service will then surely be a way in establishing my credibility.

Then I am very convinced he is making extraordinary claims about those tennis balls. Even though he is stating some truths (e.g. vibration isolation) in his case it does not make everything true (Fallacy of association). I am also convinced that no one will blame me if I am especially sceptical about his “truth”. The burden of proof is not mine as I made no such extraordinary claims. I am just sceptical about the specials characteristics of those tennis balls. I think it is possibly snake oil and that ordinary 2nd hand Dunlop tennis balls will work equally as well.

Sure thing. Why not. You can contact me via PM to get my exact address in Cape Town. Please send as many as you do believe I need to experience the full results, at your earliest convenience. If you are based in Cape Town please come and visit and we can experience it together.

I will even invite a few "golden ear" formunites to come and experience your product.
